| 摘 要： | 采用砂滤管法研究不同有机物料中有机碳及氮、磷、钾分解规律。结果表明:不同有机物料中有机碳在埋管初期分解较快,后期分解较慢,分解趋势为玉米秸秆大豆秸秆玉米根茬大豆根茬;经过150 d的分解,氮、磷、钾有79.9%~90.2%、93.7%~99.0%、50.6%~78.4%被释放出来。与不调节C/N相比较,各有机物料调节C/N后有机碳分解速率加快,玉米秸秆、玉米根茬、大豆秸秆、大豆根茬平均提高22.8%、19.4%、13.9%、18.7%,尤其埋管后45 d,调节C/N能明显提高秸秆的分解速度。经过150 d的分解,有72.3%~78.1%的氮被释放出来,磷素有90%左右被释放,C/N的调节对钾素影响不大。 |

| Abstract: | Sand strainer tube method was used to determine decomposition regularity of different organic material of organic C and N, P, K. The results showed that organic C decomposition rate of different organic material were faster at the beginning of buried tubes, and slower at the later. The trend of organic C decomposition rate was corn stalk>soybean stalk>corn root stubble>soybean root stubble. After 150 days, N, P and K release rate were 79.9%～90.2%、93.7%～99.0%、50.6%～78.4%. Compared with no adjusting C/N , adjusting C/N accelerates organic C decomposition rate of various organic materials, Corn stalk, corn root stubble, soybean stalk, soybean root average of 22.8%, 19.4%, 13.9%, 18.7%, decomposition rate had obviously improved especially 45 days after embedding. And N was decomposed 72.3%～78.1%, P was about 90%, but K has not obvious influence. |
